As a bonus action on each of your turns, you can mentally command any creature you've animated with that spell if the creature is within 120 feet of you (if you control multiple creatures, you can command multiple creatures. one or all at the same time, issue the same command to each). You decide what action the creature will take and where it will move on its next tour, or you can issue a general order, such as guarding a particular room or hallway. If you don't issue an order, the creature will only defend against hostile creatures. Once an order is given, the creature continues to follow until its task is complete. The creature is under your control for 10 min, after which it ceases to exist and returns to nothingness
